OIL-BURNER.

Application led .Tune 29, 1918.

To all 'whom it may concern Be it known that I, ALBERT E. VAN! Asser-In, a citizen of the United States, residing at Dearborn, county of Vayne, State of Michigan, have invented a certain` new and useful Improvement in Oil-Burners, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to oil burners shown in the accompanying drawings and more particularly pointed out in the following specification and claims.

One of the objects of my invention is to provide an oil burner adapted for use in stoves, ranges, furnaces and other like installations, and which is simple in construction and efficient iny its operation and notv apt to get out of order or require repairs.

Another object of the invention is to provide for the introduction of steam along with the fuel to assist combustion and otherwise increase the efliciency of the burner, the construction and operation being such that the passage. of steam from the boiler to the burner serves to carry with it the liquid fuel which, co-mingling with the steam, is vaporized, to be consumed upon its discharge from the end of the burner.

Another object of the invention is to provide for the automatic cutting oif of the delivery of fuel to the burner in the event of the flame being extinguished through any cause. The construction and arrangement of the parts being such that the level of the fuel delivered to the burner is below that of the discharge outlet from the latte1,-and as the feeding of the fuel to the burner is dependent upon a jet of steam for its operation it will be apparent that should the flame be extinguished the water delivered to the boiler cannot be evaporated and hencethe steam necessary to insure the delivery of the fuel to the burner will not be supplied. Thus the stove or furnace cannot become flooded with fuel in the event of the flame being extinguished, either through accident or design, means beingl also provided for cutting olf the delivery of water to the boiler as soon as it ceases to be converted into steam.

Another object of the invention is to pro- Specicaton of Letters Patent.

Serial No. 242,559.

vide for the introduction of an electric heating element whereby the water may be initially converted into steam and the liquid fuel vaporized, the electric heating element being withdrawn upon the normal operation of the burner.

With the foregoing and other .objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention as herein disclosed without departing from the spirit of the same.

llng-the accompanying drawings forming part of this speciiicationzf l Figure l is a side elevation of the device yas installed in a stove5-a fragment of which is shown in section together with the water and fuel supply tanks (the latter being shown in section) and the pipe connections to the burner.

Fig. 2 is a longitudinal sectional View through the boiler and pipe connections showing the electric heating element in position. v

Fig. 3 is a fragmentary sectional view through the water tank and supporting hopper taken at right angles to the viewof the tank and hopper shown in Fig. l.

Fig. 4 is a longitudinal sectional view of the fitting with which the steam and fuel pipes are connected for the delivery of steam and fuel to the burner.

Referring now to the letters of reference placed upon the drawings A, denotes the lire box of av stove. B indicates a tubular boiler preferably constructed of cast iron. C, is a water pipe extending into the boiler connected with a water supply tank F. The pipe C is inclosed in a relatively larger pipe forming a steam jacket D, tted at one end with a bushing D to prevent the escape of steam at that point.

D2 is a drain 0E cock in the pipe D for the removal of sediment or other matter. E indicates a valve, having a graduated handle adapted to be operated in connection with the pointer E, for controlling the delivery of water from the tank E. Gr, is a supporting cup and hopper, provided with a perforated partition G, adapted to trip the valve f to release the water from the tank E, the

water being discharged as rapidly as consumed due to the lowering of the water level inthe cup and hopper in a manner well understood. G2 is a second partition spaced from the partition G having a central opening G3, beneath which is a trough Gf, for leading the water discharged to one side of the hopper. G5 isV a glass or window set 1n the wall of the hopper against which the water is discharged, in order that the delivery of water may be observed. G6 is an air vent. H, denotes brackets for securing the tank to a wall or other support.

l, indicates a fuel tank supported in a funnel shaped cup J, also supported by brackets and provided with a partition d, adapted to trip the releasing valve 1 controlling the discharge of fuel from the tank. K is a fuel pipe leading from the cup d to a fitting L located within the fire boi; of the stove or furnace. K indicates a. valve for controlling the delivery of fuel through the open end of the pipe K. M denotes a nipple having a right and left thread at its respective ends for connecting the fitting L with the elbow of a pipe N, located Vwithin the boiler B and open at its forward end for the admission of steam. The fitting L is formed with a funnel-shaped chamber L', the contracted end of which opens into a passage connected with the steam pipe N. rlthe enlarged end of the chamber L opens into a goose-neck pipe P fitted with a downwardly directed elbow P in which is supported an annular plug P2 having a contracted opening for the discharge of gas. The liquid fuel pipe K opens into the fitting L adjacent tothe inlet from the steam nipple M and between it and the opening into the gooseneck pipe P. Suspended beneath the boiler is a llame deleotor Q, open at Q for the passage of the flame. R is a tube close-d at one end preferably formed of copper and supported in the wall of the boiler which is adapted to receive a suitable electric heating element S, connected with a source of electric supply for initially evaporating the wat-er delivered to the boiler, and for vaporizing the liquid fuel.

Having indicated the several parts by reference letters the construction and operation of the burner will be readily understood.

To start the burner water is first delivered to the boiler and the electric heating element inserted in its tube and current turned on. If desired however other means may be eniployed to evaporate the water and to vaporize the fuel. |Phe valve K controlling the discharge of fuel froin the fuel tank is then adjusted and upon the passage of stea-in from the boiler through the fitting L the liquid fuel will be drawn from its relatively lower level up into the fitting where it will quickly vaporize, and commingling with the steam pass out through the goose-neck pipe P to the discharge end 4of the burner where it is ignited, the flame being projected against the deflector which serves to direct it against the boiler and to spread it over a relatively large area.

rPhe delivery of water through the jacketed pipe C into the boiler may be properly regulated by the valve E which is tted with a graduated handle for that purpose. The water delivered into the boiler from the end of the pipe C is instantly converted into steam and passes thence through the open end of the pipe N which in turn delivers the steam tothe fitting L as before explained.

ln the event of the flame being accidentally extinguished there will be no danger of the iirebox of the stove or furnace becoming flooded with liquid fuel, because as soon as the boiler ceases to generate steam the fuel cannot be drawn to the fitting Lg-the fuel level being relatively lower than the fitting. Therefore upon the flame being eX- tinguished, either through accident or design, both the supply of liquid fuel and of water will be automatically cut o from the device.

Having thus described my invention what l claim is 1. In an oil burner, a boiler, a tube closed at one end and supported in the wall of said boiler to receive an electric heating element,

an electric heating element, a water supply tank connected with the boiler, means for' controlling the delivery of water to the boiler, a pipe for conducting steam from the boiler, a fuel supply tank, a pipe for conducting fuel from the fuel supply tank, a burner, and a fitting connected with the burner and with steam and fuel pipes for the delivery of the combustible mixture to the burner.

2. 1n an oil burner, a boiler, a water supply tank, a water pipe connection between said water supply tank and the boiler, a pipe surrounding the water pipe connection adapted to admit steam from the boiler around said water pipe connection, a valve for discharging sediment directly therefrom, means for controlling the delivery of water 'to-the boiler, an open ended pipe located within the boiler, a steain pipe and separate from the water pipe connected with last named pipe, a fuel supply tank, a pipe for conducting fuel from the latter, a burner, and a fitting connected with the fuel and steam pipes adapted to deliver the combustible mixture to the burner, said fitting being disposed in a plane beneath the horizontal plane of the burner and adjacent one end of the boiler.

3. In an oil burner, a boiler, a water supply tank connected with the boiler, a steam pipe leading from the boiler, a fuel supply tank, a pipe leading therefrom, a valve for controlling the delivery of fuel through said pipe7 L burner, disposed in e single horizontal plane with the boilei` and a fitting connected with the burner and With the steam and fuel supply pipes, said itting formed with a tapering chamber through which the steam and fuel pass und Cominngle on the Way to the burner.

In testimony whereof, I sign this specilioation in the presence of two Witnesses.
